Actually I would.  The material is something like A356-T6 which has the great advantage of high post-yield ductility. It is selected for exactly this situation...the ability to sustain damage beyond yield without fracture.  In fact, if the "repair" attempts to straighten it and proper procedure is not followed, it could cause more damage, even though it may look OK.  A proper repair would involve annealing the material, followed by straightening, followed by a new heat treatment.  I would bet that is not done by most repair shops.  So unless you are certain the shop knows how to handle this,  yes, I would leave it alone.  You could die-pen the area to check for cracks but from the looks of it you are fine IMO.

I've been a mechanical engineer for over 20 years and am aware of what processes are required.

Still doesn't change the fact that the wheel now has an inherent weak spot. I personally wouldn't want to hit another pothole or whatever in that same spot again. I definitely couldn't reccomend leaving it alone to someone else as well just because it still holds air.

Ok fair enough.  But if the OP goes the repair route, rather than replacement, it is important that the repair be done correctly.  The average corner garage will hit it with a blow torch and hammer or die-and-clamp it back into shape.   That absolutely will destroy the factory heat treat, will put in a bunch of residual stress, and compromise integrity...far more than the damage that was done in the first place.  It's a personal call, and as I said, they could dye-pen the area if they are really concerned about it.  If the motivation is structural integrity, and not just looks, I would likely opt for replacement.

Looks just like mine and I have well over 10000 miles on it bent. Doesn't lose air ballences fine unless I'm checking the air pressure don't give it a thought. Unless it bothers you I suggest you do the same. The wheal on my FZ1 had similar damage or worse and put 50000 miles on it like that.

A new wheel costs £750 from memory.

Mine took about 2 hours to fix and cost my £70.

Mine costed 440euros to fix and took 2 weeks.
(Coatings removed, fixed and new paint on even with not damage to paint)

But this was professionals that only deals with damaged wheels.

They had your pants down then.

Didn't offer you some magic beans at the same time did they?

Just incase anyone else is in the UK and doesn't want to get ripped off too. Google Thersby Group if you require any wheel repairs.

Last event of the track day season I had an off track excursion on my zx6r.
During the fall/winter I made all the repairs - thought I was thorough.
Late in the next season I had to replace worn tires.
While swapping on the new tires I discovered a damaged area on my front rim about the same or worse than yours.
I was very upset/worried about it.
Then my track buddy pointed out that I just went pretty much the whole season with that rim without any issues under track/race speeds.
I have gone thru 2 set of tires since finding the bent rim lip.
Balances fine and never have had an issue even with starting cold temps of 29 or 30psi.
I would leave it be.
But obviously its you and your bike and you need to sleep at night.
YMMV.

A few years ago my friend Rusty hit a pothole hard on his Speed Triple on one of our annual Monterey rides.  This was approximately 450 miles from home.



Look closely.  You can see daylight through the tire seat of the rim where it split.  Well, we were out in the middle of nowhere, not a chance of phone reception in any way.  So he rode it, slowly at first, then with growing confidence.  He hit speeds of over 100mph on the way home, and that tire held air just fine.

He bought a replacement wheel and now uses that rim as a wall clock, but it is a testament to how well modern tire technology and rim manufacturing technique work to make a tight seal.
Just keep your head held high

That must have been a monster of a pothole.
Now that rim I would replace.
100mph on that? U nutz.

If that was a carbon fibre wheel, it would have fractured and may have had a bad ending. Ductile aluminum = a good choice for road use.  :152:

I broke a wheel on a CB1000R before buying a 15 S1KR. I had never damaged wheels before, but after the CB experience, I bought a wheel & tire rider on my 3 yr extended warranty. I think it was about $300 extra. Over the next 30K miles, I broke both wheels in separate incidents. The insurance covered both wheel replacements including tires. I bought it again when I bought my 17 S1KR. It has forged wheels and I haven't had any problems with them in 23K miles.
